onyx t68 has 265 ppi, android 4.0,1 GHz Cortex-A9 dual core cpu, 512 MB RAM, while yotaphone has 235 ppi, android 4.4.3 ( possible update to 5 lollipop) and .. here the difference
Qualcomm Snapdragon 800 (2.26Ghz quad core) and 2GB RAM this means responsiveness, as I can see for all the reviews for the YP2 vs the sluggishness of onyx t68.
Another important point you run android 100%, not customed launchers, you decide all, because Android is customizable, you build your system.
But most important: you get an amoled screen with 16 M color, the only technology that allow lcd to be readable under the sun, with the LCD responsiveness.... this means you go on lcd,
super fast, select your book, open your colored nice cover jump to the page you want and you press the mirror function and in one sec turning the phone you can read! This is an HUGE advantage, I get frustrated when I want to scroll my collections, or switch between books on ereaders like T68, so I understand you fully.
edit: but if one does not tolerate lcd at all, can use also only the lcd screen, although not optimally big, just 4,7 inches. Possibly will be possible to use in landscape mode, I do not know that at the moment, but for me is super fine, i can enlarge character, after all for years I read newspapers with small rows, and I loved because i could read one row casting my eye on the center of the row

Dear chap, is on my agenda, get tuned, I know that you love reading and cannot stand the eye strains due to your age, I am a developer I know what you mean, at the moment I use a strategy to relax the eyes, looking after 5 min I stare the lcd screen, to a whatever corner in the office, or in the house, for 20 seconds, at office I have a window with some magnificent autumn trees in a really beautiful location in Amsterdam, it definitely helps a lot, together to close the eyes once in a while, and have a deskcycling, that is amazing, you can use it also if you are 76( one of my favorite human beings, started to do 42 km marathons at 86 years, now is 104 and still runs), in this way the eyes get fresher because of the blood circulation.
Anyway stay tuned if you like, I will tell you everything( also if I know that 4.7 inches(vs 5 of the lcd) are not optimal, but still we can enlarge the characters


and make the device disappear in your pockets.

what a pity, I would have rather bought there, anyway with bol.com in the Netherlands I have every kind of return guarantee, if is a trusted sellers, I could buy a spare one if I will become an hard yota user, even because I love to play chess on the sun

Said that the YP2 is a little jewel, the only problem is was not known outside a niche group, because Putin was giving away as gift to the people visiting Russia, as flag of the level of technology. So there is much more involved in the lack of success of this phone, and companies... you know geeks and marketers not always read political news, basing their researches on marketing researches, but you know, there are not too many visionary steve jobs out there!

guys and I will update after the 25
EDIT did I mention the 32GB of storage? Just if you want to put the Alexandria library on your device
